BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a seat cushion, and more particularly to a portable multifunction seat cushion that can be carried conveniently.

2. Description of Related Art

A conventional chair is made of wood, plastic or metal material with high strength and hard texture to increase a supporting strength of the conventional chair. Furthermore, the conventional chair has a seat cushion that is made of sponge and cloth with soft texture mounted on a sitting part of the conventional chair to increase the softness and comfort of the sitting part of the conventional chair.

Although the conventional chair has the seat cushion mounted on the sitting part of the conventional chair, the seat cushion is securely sewed around or attached to the sitting part of the conventional chair. Then, the seat cushion cannot be separated from the sitting part of the conventional chair for cleaning or replacement according to the user's need. In addition, if the seat cushion of the conventional chair cannot provide a comforting effect to the user, the user may easily sit with poor posture and feel stiff and sore after remaining sedentary for a long time.

Currently, a conventional detachable seat cushion has been provided on the market, and the user can choose a detachable seat cushion according to personal preferences, and then place the chosen detachable seat cushion on the sitting part of the conventional chair easily. However, the conventional detachable seat cushion has a large volume and cannot be folded to carry conventionally. Therefore, the conventional detachable seat cushion is most securely attached on a chair or is mounted on a fixed place and cannot be carried out for use such as hiking, picnicking or sporting. In addition, because the conventional detachable cushion is inconvenient to carry, so even if the ground is uneven, wet or dirty, it cannot be used to isolate the wet or dirt of the ground or to buffer the unevenness of the ground. Furthermore, the conventional detachable seat cushion can only provide a sitting effect to the user without any other functions.

To overcome the shortcomings, the present invention tends to provide a portable multifunction seat cushion to mitigate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a portable multifunction seat cushion that can be carried conveniently.

The portable multifunction seat cushion in accordance with the present invention has a body, a fixing unit, a carrying unit and a storage unit. The body has a middle, an inner surface, an outer surface, two opposite sidewalls and two folding lines. The folding lines are formed on the middle of the body at an interval and are parallel with each other and the opposite sidewalls of the body. The fixing unit is mounted on the opposite sidewalls of the body to fasten the body when the body is folded. The carrying unit is attached to the body to provide a carrying function.
